Just checked the MTM sport coat I have . . . find the box labeled "Tessuto, Fabric, etc." and in that area should be the description of the fabric (e.g. "100% wool" or "80% wool, 20% silk"). Immediately above that description but still in the same box is a code # (e.g. 03F019), and next to that code number is a letter (in this case, "I"). The "I" is the fabric grade for this jacket.
FYI: I have another Zegna sport coat that I bought at a Neiman Marcus sale a couple of years ago. The tag is slightly different, and while the fabric description and code is there, the letter-grade designation is not. Perhaps it is somewhere else on the tag or maybe it's only on EZ suits bought from their stores, I'm not sure. When I first bought the jacket, I had no clue about the letter designations. Since I found out about it, I've always been curious as to where I might find it for that jacket. Maybe I'll ask my Zegna guy the next time I'm in the store.
And if/when you're doing MTM, it's much easier to find since the individual swatches should be labeled accordingly.
